iMessages change text color - ios

Question

My app is showing iMessages ViewController via UIActivityController. However, the colors of labels are all messed up (blue so they are barely visible). I think this is because the view controller is using my app's tint color. See below.
How can i fix this?
thanks!

I ran into something similar with presenting MFMailComposerViewController modally. Try setting the appearance of your app's tint color to nil when presenting the activity controller, and then back to your desired app tint when it completes. Here's what I did with MFMailComposer. You should be able to modify for your activity controller:
...
[[UINavigationBar appearance] setBarTintColor:nil]; // Set to default before presenting
MFMailComposeViewController *mailVC = [[MFMailComposeViewController alloc] init];
mailVC.mailComposeDelegate = self;
[self.navigationController presentViewController:mailVC animated:YES completion:nil];
...
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
[[UINavigationBar appearance] setBarTintColor:MyAppsCustomColor]; // set it back when finished
[self.navigationController dismissViewControllerAnimated:YES completion:nil];
}
EDIT
When I use this solution, it changes the nav bar appearance in the presented modal that is selected in the activity view controller (messages, mail, etc). I'm setting my app's nav bar appearance to blue in my delegate, and then back to blue in the completion block. The app's nav bar remains blue, and the presented messages/mail modal is shown with the default light gray nav bar.
UIActivityViewController* avc =
[[UIActivityViewController alloc] initWithActivityItems:#[#""]
applicationActivities:nil];
avc.completionHandler = ^(NSString *activityType, BOOL completed) {
// ...
dispatch_async(dispatch_get_main_queue(), ^{
// Set tint color back to blue.
// This block is executed whether the user finishes or cancels.
[[UINavigationBar appearance] setBarTintColor:[UIColor blueColor]];
[[self navigationController] setNeedsStatusBarAppearanceUpdate];
});
};
[[UINavigationBar appearance] setBarTintColor:nil];
[self presentViewController:avc animated:YES completion:nil];
